I report on work, done with Rajan Gupta and Greg Kilcup, using staggered fermions to study weak matrix elements in quenched QCD. I give an update on the ΔI = 1/2 rule and on matrix elements relevant for ϵ'. I show results of a study of the dependence of BK on non-leading terms in the chiral expansion. I present our first results for BK from a quenched calculation at $$β$$ = 6.4 on 323 x 48 lattices, based on an ensemble of 12 configurations.
